UNITED STATES ALFRED DENIS, OF MONTREAL, QUEBEC, CANADA.

CANNING APPARATUS.

Application filed September 24, 1923. Serial No. 664,459.

To all whom. it may GOHOQWt-f Be it known that I, ALFRED DENIS, aBritish subject, residing at 314 Notre Dame St. east, in the city ofMontreal, in the Province of Quebec, in the Dominion of Canada, haveinvented certain new and useful Improvements in Canning Apparatus; and Ido here by declare that the following is a true, clear, and exactdescription of the same.

The present invention relates to improvements in a canning apparatus,and relates to that type in which the furnace is entirely surrounded bywater. The invention contemplates an extension easing into which thefurnace casing is extended, thus providing means for handling a large orsmall amount of water. The invention further resides in novel means foroperating the doors which control the passage of the fuel gases into theextension chamber.

The invention is hereinafter fully described and illustrated in theaccompanying drawing, in which Figure 1 is a side elevation of a deviceaccording to the invention;

Figure 2 is a top view, the cover and pans having been removed;

Figure 3 is a cross section on line 33 of Figure 2, the pans beingillustrated in section; and

Figure 4 is a modified form of the boiler cover, a portion of the boilerbeing shown in section.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawing 1 is a boiler preferably of rectangular shapeand provided with a pyramidal cover 2 on its upper open end. 3 indicatesa furnace casing mounted in the boiler and having its bottom, top, sidesand one end suitably spaced from the interior sides of said boiler, saidfurnace casing having an opening 4 into the forward end of the boilerand which may be closed by the door 5, the said furnace casing beingpreferably longitudinally disposed somewhat on one side of the center ofthe inside of said boiler and made to project into the extension casing6.

The extension casing 6 is preferably provided at one end of said boilerand is provided with a cover 7. The furnace casing 3 extending into saidportion 6 is also suitably spaced at its bottom, top sides and end fromsaid casing and projects at 8 beyond the width of the casing 3. To saidextension 8 is suitably connected the horizontal and parallel flue 9which extends from said extension 8 back into the boiler l andterminates outside of said boiler with the chimney 10. Approximatelyintermediate of its length, the flue 9 communicates with the furnacecasing 3 by means of the right angular flue 11. The flue 11 ispreferably closed by means of the sliding door 12. 13 is a doorpivotally mounted at 14 in the bottom of the furnace casing and locatedat the end of the boiler 1, said doors 13 and 12 being simultaneouslyoperated by means of the rod 15.

The rod 15 is provided at one end with the handle 16 which projectsoutside of the boiler 1 and is secured at 17 to the sliding door 12, sothat when the rod 15 is pushed longitudinally and inwardly the door 12will be closed. Simultaneously the door 13 will be opened as indicatedin dotted lines in Figure 3, by means of the pivoted link 18 which isconnected at one end to the other end, of said rod 15, and at its otherend, is pivotally connected to the door 13. By pulling said handle 16outwardly the door 13 is operated to close a portion of said furnacecasing 3 and simultaneously open the door 12, thus allowing the productsof combustion to enter the flue 9 by means 01 the flue 11.

The object of the flue 11 and the doors 12 and 13 is to heat the casing6 simultaneously with the boiler 1 when desired, or heat only thecontents of the boiler 1. The boiler 1 and the casing 6 are preferablyfilled with water. 19 are trays suitably disposed across the casing 23,and flue 9 in said boiler and easing 6. In said trays the canned goodsare placed for cooking. The boiler 1 and casing G are also each providedon one side with taps 20 for emptying them of water. The boiler 1 hasalso provided at its forward end a tray 21 to prevent the ashes fromfalling to the ground.

In Figure 4 is disclosed a modified form of cover for the boiler 1. Inthis modified form the cover which is pyramidal is provided at its apexwith the nipple 22 which preferably connects with the inner side of saidcover and on which is mounted the hose 23. The object of said hose is toprovide suitable means for the steam to escape from said boiler.

What I claim as my invention is 1. A canning apparatus comprising aboiler; an extension casing secured to said boiler; a furnace casingsecured in said boiler and extension casing and having bottom, side andtop portions; a flue in said boiler arranged parallel to and connectedto said furnace casing in the extension casing; a right-angular flueconnecting said furnace casing and said first-named flue together; adoor hinged to the bottom portion of said furnace casing adapted toshutoff that part of the furnace casing which projects into saidextension casing; a sliding door secured to the side portion of thefurnace casing and adapted to close the opening into the right angularflue; trays arranged on the top por tion of the said casings; and meansfor operating said doors.

2. A canning apparatus comprising a boiler; an extension casing securedto said boiler; a furnace casing secured in said boiler and extensioncasing; a flue in said boiler arranged parallel to and connected to saidfurnace casing in the extension casing; a right-angular flue connectingsaid furnace casing and said first-named flue together; and meansincluding a pair of doors for controlling the passage of the flue gasesthrough the furnace casing or said extension casing.

3. A canning apparatus comprising a boiler; an extension casing securedto said boiler; a furnace casing secured in said boiler and projectinginto said extension casing; a flue in said boiler secured to saidfurnace casing; a right-angular flue connecting said furnace casing andsaid firstnalned flue together; and means for closing said extensioncasing to guide the flue gases through the right-angular flue.

4:- A canning apparatus comprising a boiler; an extension casing securedto said boiler; a furnace casing secured in said boiler and projectinginto said extension casing; furnace casing inthe extension casing; arightangular flue connecting said furnace casing and said first-namedflue; a hinged door in said furnace casing adapted to shut off that partof said furnace casing which projects in said extension; a sliding doorin said furnace casing adapted to close the right-angular flue; andmeans for simultaneously operating said doors to shut off the flue gasesfrom the furnace casing extending into the extension casing and guidethem through the right-angular flue.
